Overview
The BAV21WHE3-TP is a silicon epitaxial planar small signal diode from Micro Commercial Components, housed in an SOD-123 package. It features a maximum repetitive peak reverse voltage of 250V and a continuous power dissipation of 410mW. The device supports a forward DC current of 250mA and a peak forward surge current of 1A. Electrical characteristics include a typical reverse recovery time of 50ns and a total capacitance of 1.5pF at 0V bias. It operates within a junction temperature range of -55°C to +150°C and maintains a thermal resistance of 305°C/W.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- Halogen-free green device construction with UL 94 V-0 flammability rating
- Moisture sensitivity level 1 classification for handling ease
Applications
- High-speed switching circuits
- Clamping and protection applications
- Automotive electronic systems requiring AEC-Q101 compliance
Procurement Notes
Verify the specific part number BAV21WHE3-TP against official Micro Commercial Components documentation to confirm electrical parameters and packaging details. Ensure compatibility with SOD-123 footprint requirements. Confirm RoHS compliance status via the datasheet. Purchase only from authorized distributors to guarantee genuine parts and traceability as per manufacturer guidelines.
Selection Notes
Select this component when a 250V reverse voltage rating is required alongside high-speed switching capabilities. The SOD-123 package offers space efficiency compared to larger alternatives. Consider the 50ns reverse recovery time for frequency constraints. Verify thermal management needs given the 305°C/W thermal resistance and 410mW power dissipation limit under expected operating conditions.
Part Context
This device belongs to the BAV19WHE3 through BAV21WHE3 series of small signal diodes manufactured by Micro Commercial Components. All variants share identical physical dimensions and general electrical profiles, differing primarily in their maximum repetitive peak reverse voltage ratings. The BAV21WHE3 represents the highest voltage variant in this specific lineup.
Replacement Considerations
Direct substitutes within the same family include BAV19WHE3 and BAV20WHE3, provided the lower reverse voltage ratings are acceptable for the circuit design. Verify that alternative components meet the same AEC-Q101 qualification if automotive use is intended.
